Accton Technology ES3528M-SFP manual Igmp Filter and Throttling Port Configuration

3 Configuring the Switch

•An IGMP profile or throttling setting can also be applied to a trunk interface. When ports are configured as trunk members, the trunk uses the settings applied to the first port member in the trunk.

•IGMP throttling sets a maximum number of multicast groups that a port can join at the same time. When the maximum number of groups is reached on a port, the switch can take one of two actions; either “deny” or “replace”. If the action is set to deny, any new IGMP join reports will be dropped. If the action is set to replace, the switch randomly removes an existing group and replaces it with the new multicast group.

Command Attributes

•Throttling Action Mode – Sets the action to take when the maximum number of multicast groups for the interface has been exceeded. (Default: Deny)

-deny - The new multicast group join report is dropped.

-replace - The new multicast group replaces an existing group.
